I noticed that, if you search a Phriction document, the results do not mention "Phriction" nor "wiki" so it can be confusing.

Instead, see that Maniphest mentions itself. So, it's more clear:
{F272273}
Test for Diffusion. See that it just mentions "Repository" (it is very clear and simple):
{F272276}
== Proposed solution ==
Somehow improve the Phriction search results to also mention "Wiki page" or something like that in the footer. Just like a Diffusion repository just says "Repository".
